FSCN1 and carcinoma: FSCN1 is regulated by several signaling pathways (AMPK/mTOR, Wnt/β-catenin, and MAPK) and is overexpressed in various human carcinomas including gynecological cancers; however, understanding the exact molecular mechanisms underlying FSCN1 deregulation and interaction with other genes and oncoviruses, especially in gynecological cancers, is still nascent.
